Abstract
A synergistic effect of surface plasmons (SPs) and surface passivation on ZnO thin film optical performance was studied. The ZnO thin film of thickness of ca. 40â¯nm was deposited on Al concave arrays with a period (Dc) of about 125, 252, and 340â¯nm. Next, the Al2O3 coating thickness was tested with respect to UV light enhancement. About 20-fold enhancement of the UV emission was achieved upon simultaneous application of Al concave array with Dcâ¯ââ¯340â¯nm and 10â¯nm thick Al2O3 coating. Moreover, it was found that the Al concave array with Dc of ca. 125â¯nm does not sustain the SP resonance in UV region.
